Ganoderma lucidum Mycelia Mass and Bioactive Compounds Production through Grape Pomace and Cheese Whey Valorization

mycolabadmin

Researchers successfully grew Ganoderma lucidum mushrooms using leftover materials from wine and cheese production instead of expensive lab chemicals. The mushroom mycelium produced valuable compounds called polysaccharides that have antioxidant and health-promoting properties. This approach reduces food waste while creating beneficial substances, making it economically and environmentally sustainable.

Enzymatic Activity and Nutrient Profile Assessment of Three Pleurotus Species Under Pasteurized Cenchrus fungigraminus Cultivation

mycolabadmin

This study tested growing oyster mushrooms on a special grass called Cenchrus fungigraminus that was heat-treated to remove harmful organisms. Three types of oyster mushrooms were grown, and researchers measured the enzymes they produced and the nutrition in the harvested mushrooms. The oyster mushroom species Pleurotus ostreatus grew fastest and produced the best yields, and the grass substrate proved to be an effective and affordable choice for small-scale mushroom farming.

Suitability of maize crop residue fermented by Pleurotus ostreatus as feed for edible crickets: growth performance, micronutrient content, and iron bioavailability

mycolabadmin

Researchers tested whether crickets could be raised on inexpensive mushroom-fermented corn stalks as an alternative to costly grain feeds. While the fermented stalks made iron more absorbable by the human body, the crickets actually grew worse on this feed compared to unfermented stalks. The study suggests that combining mushroom and cricket farming, while theoretically appealing for sustainability, may not work well in practice due to poor cricket survival and growth on spent mushroom substrate.

Potential biodegradation of polycyclic aromatic hydrocarbons (PAHs) and petroleum hydrocarbons by indigenous fungi recovered from crude oil-contaminated soil in Iran

mycolabadmin

Scientists isolated fungi from oil-contaminated soil in Iran to find species that can break down petroleum pollutants. Two fungi species, Alternaria tenuissima and Epicoccum nigrum, showed exceptional ability to degrade harmful oil compounds called PAHs. When applied to contaminated soil in the laboratory, these fungi successfully eliminated over 70% of the long-chain hydrocarbons. This research offers a natural and cost-effective way to clean up oil-spilled soil without using harsh chemicals.

Mycoremediation: Expunging environmental pollutants

mycolabadmin

Fungi can be used to clean up environmental pollution from industrial waste, pesticides, and heavy metals. Unlike expensive chemical treatments, fungal mycoremediation is cost-effective and environmentally friendly. Fungi produce natural enzymes that break down harmful pollutants into harmless substances, making it a promising solution for protecting soil and water contamination.

Organic Nitrogen Supplementation Increases Vegetative and Reproductive Biomass in a Versatile White Rot Fungus

mycolabadmin

Researchers studied how adding nitrogen from plant litter affects the growth and mushroom production of a wood-rotting fungus called Cyclocybe aegerita. They found that adding the organic compound adenosine—which naturally occurs in plant litter—significantly boosted both the fungus’s vegetative growth and the production of mushrooms. The results suggest that fungi living in wood benefit from being able to absorb nitrogen-rich compounds from nearby plant material, which improves their ability to grow and reproduce.

What Inspires Biomimicry in Construction? Patterns, Trends, and Applications

mycolabadmin

Nature has already solved many design problems that architects and engineers struggle with today. This research examines how 70 recent studies have borrowed ideas from organisms like termites, coral reefs, and lotus plants to create better buildings. The study finds that most biomimetic applications focus on improving function and structure—like using termite mound ventilation principles for energy-efficient buildings—but there’s huge potential in learning from how nature heals itself and adapts in real-time.

Bioremediation of Landfill Leachate with Fungi: Autochthonous vs. Allochthonous Strains

mycolabadmin

This research compared two approaches to cleaning landfill leachate using fungi: using fungi naturally found in the polluted water versus using well-studied fungi species from laboratory collections. Scientists tested how effectively these fungi could remove color and toxins from contaminated wastewater. The study found that both types of fungi worked reasonably well, but through different mechanisms—some fungi absorbed the pollutants while others chemically broke them down using special enzymes.

Unlocking the magic in mycelium: Using synthetic biology to optimize filamentous fungi for biomanufacturing and sustainability

mycolabadmin

This comprehensive review explores how scientists can use modern genetic engineering tools to improve filamentous fungi (molds and mushrooms) for producing valuable products like antibiotics, enzymes, and sustainable food and materials. The authors explain that while these fungi naturally excel at breaking down plant material and producing useful compounds, they haven’t received as much attention from genetic engineers as other microorganisms. By applying techniques like CRISPR gene editing, computational modeling, and directed evolution, researchers can make fungal strains grow faster, produce higher yields, and use cheaper feedstocks, making industrial production more efficient and environmentally friendly.

Immunomodulatory Effects of Edible and Medicinal Mushrooms and Their Bioactive Immunoregulatory Products

mycolabadmin

Mushrooms have been used for health for thousands of years and contain special compounds that help boost the immune system and fight cancer. Scientists have identified several key active ingredients in mushrooms like polysaccharides and proteins that can activate immune cells and reduce tumors. Some mushroom products like lentinan from shiitake mushrooms have already been approved as cancer treatments in Japan. While most evidence comes from lab studies, ongoing research suggests mushroom-based medicines could become important therapeutic options.
